mm CLIPPER.

Application filed April 26,

This invention relates to hair clippers and its main object is toprovide a power 0 erated clipper of simple, durable and eflicientconstruction.

Another object is to provide means embodied in the clipper for coolingthe clipper blades and preventing the hair from working into theclipper.

Another object is to provide means for tightening the clipper bladeswithout unduly increasing friction.

Other objects and advantages of the device will be apparent from thefollowing specification and the accompanying drawmg.

in the drawing Figure 1 is a longitudinal vertical section of theclipper.

Figure 2 is a plan view of the clipper, with the upper half of thehousing removed to show the working mechanism.

Figure 3 is a plan view of the clipper, assembled.

Figure 4; is a detail of the blade oscillating eccentric or cam and theassociated parts.

In constructing and assembling the elements of my invention, I providethe conventional clipper base 1 having the lower half 3 of a housing 2secured thereto. Bearing standards 5 and 6 are rigidly secured in thelower half 3 of the said housing 2, and have ball bearings 7 mountedtherein. The forward standard 5 is provided with air apertures 8 cuttherein near the lower half of the housing. A drive shaft 9 isjournalled through the ball bearings 7 and has its forward end reducedas shown at 10. An eccentric or cam 11 is adjustably secured-upon thereduced and extended end 10, by means of a set screw 25, and is adaptedto engage and rotate between the prongs 26 of a forked pivot bar 12mounted upon a pivot stem 13 located between the standard 5 and thecllpper base 1. The forward end of the pivot bar terminates in a finger14 adapted to engage a recess or socket 18 formed in a movable oroscillating clipper blade 15. The said clipper blade is mounted upon theclipper base 1 by means of apertures 16 cut in the said clipper bladewhich are engaged by guide pins 17 secured in the clipper base 1.An'askew-set fan blade 19 is secured to the shaft 9 between thestandards 5 and 6, and is adapted to drive a current of air through theair apertures 8. The upper end of the over the screw .20

said pivot stem 13 is threaded as shown at 20, to permit releasablysecuring the pivot bar upon the said pivot'13 by means of a nut 21. Apressure plate 22, carrying ball bearings 23 at itstherethrough, and thesaid ball bearings are ad ustedto nicely bear upon the upper side of theblade 15, while the rear end of the plate has a bearing upon thestandard 5. A nut 24 is provided for securing the said pressure plate 22upon the screw 20 and adforward end, is mounted which passes medlallyjusting the tension of the ball bearings 23 upon the said clipper blade15. 'The upper half 4 of the housing 2 is adapted to frictionally engagethe standards 5 and 6 for enclosing the working mechanism of the saidclipper.

1n operation, the rotation of the shaft '9 by means of any suitablepower, such as a flexible shaft connected with a motor, causes theeccentric 11 to reciprocate the pivot bar 12 and thereby reciprocate oroscillate the.

clipper blade 15 thus giving the said clipper blade its cutting motion.In rotating the shaft 9 the fan blade 19 forces air thru the apertures 8iii-the standard 5 for cooling the said clipper blade as well as forblowing the particles of cut hair therefrom. Through the adjustablemounting of the eccentric 11 upon the end of the shaft 9, the said cammay be readily moved forwardly or back-- wardly within the prongs 26,thereby correspondingly increasing or diminishing the oscillatorytravel. of the blade 15.

\Vhile I have herein described a certain specific method of constructingand assem bling the elements of my invention, it is understood same maybe varied in minor details, not departing from the spirit of myinvention as defined in the appended claim.

I claim:

A transmission unit comprising a rotatable mounted shaft having aneccentric mounted on one end of said shaft, said eccentric beinglongitudinally adjustable on said shaft, in combination with abifurcated lever having comparatively long parallel bifurcations inengagement with the operative or camming surface of the eccentric, thebifurcations and shaft being substantially parallel whereby'the throw ofthe lever may be varied by adjustment of the eccentric upon the shaft. r

In testimony whereof I aflix my signature.
